I was trying network-manager-openvpn plugin today on Lucid, I could import my configuration, DNS was set up correctly upon connection/disconnection, route imported correctly (almost :)).

One issue though is that it was also changing the default route to the VPN tunnel while this should not happen.

When you hotplug a hard drive in a virtual machine, the drive do not show in fdisk -l output until you reboot your VM.
In order to get the drive to appear, the SCSI bus need to be rescanned.

Hello Guys!

Just so you know the Team of Linux+ is going to release FREE online editon of Linux+ magazine. There will be 6 monthly issues with 60 pages each available for free download. They are looking for your support!
Write to ewa.swierczewska@lpmagazine.org for more details if interested.

Thanks!

There is a few software that will use the editor command to find out what text editor to use. Example commands will be dch to add a new .deb changelog entry, revision control softwares when prompting for a commit message ...

Lately, I have been experiencing a funny network issue when using VMware Workstation VMs with NAT interface. Roughly, the IP network was working fine, but DNS resolution was not anymore. It happened intermittently, but I could see that this mainly happened when I was suspending my laptop, going to another location and resuming.

Forcing the VM to use a public DNS would solve the issue.

I have been looking around for a while for an autotune effect (pitch correction, or whatever name you care to call it) for linux. Unfortunately everything I have found either cost money or wasn't for linux, or required special setup (wine, or other nasty things). All I could find in terms of linux autotune was people also looking for autotune. However, all the answers were unsatisfactory, either because they required manual pitch recognition (Not so good for the tone-deaf among us), or people confused it with pitch shifting in general. I eventually did find that praat (it's in synaptic), a speech analysis tool, comes surprisingly close to autotune functionality. It will give you a T-pain like effect, but it requires you to manually place the notes (although it will detect the pitch for you). I am not very experienced with praat, although this is what I figured out how to do (some of it from the original mailing list post, other I read from the manual or figured out).

Although it's GUI isn't too nice, and it isn't designed for musical manipulation, it gets the job done.

This tutorial will explain how to run a mail server with virtual domains and users using a MySQL backend to store email informations.
Postfix will be our SMTP server, Dovecot will be handling IMAP (optionally one could configure POP3 also) so that users can retrieve their email.

Another tutorial will cover SPAM fighting using DSPAM based on this implementation (yet to be done).

This tutorial was done on Debian Etch using postfix 2.3.8-2etch4 and 1.0.rc15-2etch4.

this tutorial will explain how to use a MySQL backend in order to authentication users against your Apache website.

To achieve this we will use Apache2 and its auth_mysql module.

While doing a server migration, it happens that some traffic still go to the old machine because the DNS servers are not yet synced or simply because some people are using the IP address instead of the domain name....

By using iptables and its masquerade feature, it is possible to forward all traffic to the old server to the new IP.

This tutorial will show which command lines are required to make this possible.

Vyatta is a Linux based distro that ease the set up of VPN, Routers, antivirus.... It has a really small footprint on your system as it only requires something like 800M to be installed and is based on Debian. On the top of that, it offers configuration wrappers to facilitate service settings.

This tutorial will explain how to set up 2 Border Gateway Protocol (BGP) boxes to route the traffic from one Autonomous System (AS) to the other using Vyatta.
Vyatta Community Edition 4.1.4 was used during this set up.
